I'm writing a Java application, and have a question. How can I implement a function with one parameter which should require an argument which implements multiple interfaces? For example:

interface Father
{
}
interface Teacher
{
}
public void foo(FatherAndTeacher person)
{
 // Do something
}

I know I can use two parameters, such as:

public void foo(Father person1, Teacher person2)
{
 // Do something
}

but I think maybe having a single parameter which implements both interfaces would be better.

I'm writing a java application, and find a question ,if my function's one parameter need implements multiple interface, such as I have two interface--[father_Inf, teacher_Inf](a people who is a father and a teacher), and I need both of them as my function's one parameter(such as void Do(father_Inf&teacher_Inf human)). I know I can use tow parameter, but I think maybe have a way let one parameter implement both interface, and can't google or baidu the right answer(most because I can't description clear, and which gets most no use), can who help me?Thanks very much! &Sorry about my Chinese English.
